(Cl. 22o-86) 6 Claims.

- l Our invention relates to a new and useful improvement in a fillingspout adapted for use on fuel tanks on automobiles and the like. -Theinvention relates to that class of lling spouts in which a pair oftelescoping tubes are used, one of the tubes being extendable outwardlyfrom the other and having an opening formed in its side into which thenozzle of the lling hose may be inserted. The filling spout is soconstructed and arranged that until the opening bearing tube is extendedaccess to the fuel tank through the lling spout cannot be obtained. v

It is an object of the present invention to provide a lling spout ofthis class so arranged and constructed that the extendable tube may besecured against extention so as to rendei` access to the fuel tankthrough the filling spout unob-V tainable.

Another object of the invention is the provision in a lling spout havinga pair of tubes one of which is extended beyond the other, of a lockingmeans whereby the tubes may be locked against -relative movement. l

Another object of the invention is the provision of a lmechanism wherebythe operation of the mechanism will effect an extension of theextendable tube intoposition where it may be easily gripped by the handand drawn outwardly to operative position.

Another object of the invention is the provision of means remote fromthe operating mechanism which may be operated to actuate the operatingmechanism to control a relative movement of the filling spout tubes.

Y Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made inthe detail of structure illustrated without departing from the inventionitself and it is intended that such variations and modificationsshall beembraced within the claims which form a part of this application.

Forming a part of this application are drawings in which,

In the drawings we have indicated an automobile body I5 associated withwhich is afuel tank I 6. Projecting outwardly from the fuel tank I6 is aspout 2| as shown in Fig. 3,A and connected to this spout 2l is an outertube 22, the connection being made by the flexible tube 23 and theclamping bands 24 and 25. Formed in the body or fender I1 is an openingand the fender or body I1 is bent inwardly as at I8 and then angularlyturned as at I9 and again angularly turned at 28. The tube 22 isprovided with the outwardly flared portion 26 terminating in the radialflange 21 which engages the portion I9. The portion 26 engages theportion 2n and these parts may be suitably secured together by welding,brazing or in any other manner.

Slidably mounted in the tube 22 is an inner tube or extension tube 28having an opening 29 formed intermediate its ends. This tube 28 is shownfully telescoped in Fig. 3, and in Fig. 4, it is shownv extended indotted line. When the tube 28 is fully extended, the opening 29 isexposed to provide a space into which the nozzle of the filling hose maybe inserted., The inner tube 28 is provided with a cover 30 the edges ofI which are crimped at 3| to retain a packing ring 32 of sealingmaterial formed of rubber or the like. This cover 30 engages theoutwardly turned flange 33 on the end of the inner .tubey 28 and issuitably secured thereto by brazing, welding or in any other desiredmanner. llt will be noted from Fig. 3, that when the inner tube 22 isthrust inwardly its full extent so that it is fully collapsed ortelescoped, the outer face of the cover 30 forms a continuation of theouter surface of the body or fender I1.

Inner tube 28 is provided with the axially extending groove 34 whichterminates at its inner end with a circumferentially extended groove 35.Formed through the inner tube 28 at the upper end of the groove 34 is anopening 36 which is surrounded by the inwardly pressed sleeve 31.

Mounted on the outer tube 22, is a housing 38 provided with a cover 39having the central portion pressed outwardly to provide. the channelorspace 40. Secured to and projecting outnipple 42. l of the nut 43; isa tube o its opposite end to the sheathing 45 which encloses a flexiblerod or wire 46.

This plate 52 hasthe pair of spaced apart legs-53 and 54 between which the plate formedin the plate 52. Mounted end asat V60 over the washer 59. A` plunger 95i is mounted for slidable movement into and out oi the barrel 51'. Astem 63.is `carried by the plunger and embraced by thecoil spring 64,one end 1 of this coil spring bearing against the bottom of i the barrel51 and the other. end' bearing. against the. enlarged portion fromtheenla'rged portion 95and is adapted to project-,through the'openingformed in the outer tube 22.. 1 outwardly directed flange face onU oneside to provide aA cam surface.

this retraction will not takereffect until the inner V tube 28 has beenmovedoutwardly into the full line position shown in Fig. 4. When in this`position the user of the Vvehicle may graspV the outer end of the tube28 and draw it outwardly Y manually into the dotted line position shownin Fig. f1. In this movement the plunger 62 willY ride in the groove r34and when the end Yof the groove.l '341 is reached a V,slight turning ofthe inner tube 28 will cause the plunger to engage in the.circumferentially directed groove 35 Ythus retaining the inner tube inits outwardly projected position; When it is desired to again collapsethe tube, the inner tube is turned to the position Where the plunger. 62will register with the-groove 34 and the inner tube 28v may thenV beVthrust inwardly. This inward movement will continue without disturbinglthe mechanism associated withv the housing 38 untilthepositionshownfin.v Fig. ,4 is reached, whereupon the.- inner tube will Y engagethe plunger 62` and then move it downwardly thus eiecting a slidingA ofthe'platesil and 52: to their original position. Thissliding movementwi1l,'of course,. be facilitated by the.

pressure of the springs 48 and 16. Y A Y In this manner we have provideda iilling spout'with a' pair .of .telescoping parts andV a meansAaccessible from the driversrseatwhereby ".1 the inner tube.maybe-releasecl` for movement outwardly and extended outwardlya slight'rdistance to facilitate the gripping of the tube for movement furtheroutwardly. y
